When I go to the "Info" screen, there's suppose to be a button to turn the beep on and off. It's suppose to be next to the "Adjust Clock" button. For whatever reason, I don't have the "Beep Off" button available.

Does anyone know or have a clue as to why my NAV/ML doesn't have that? I'd actually like to turn the Beep On but right now it's Off.
